How many square feet is a 12×15 room?
12 ft × 15 ft = 180 sq ft · 20 sq yd · 16.72 m² · perimeter 54 ft
The math is one line: length × width. Twelve by fifteen is where a bedroom stops feeling standard and starts feeling like a suite: 180 square feet leave a real sitting area after the bed, nightstands and dresser are in.

Questions about 12×15 rooms
Is a 12×15 room 180 sq ft including the closet?
The 180 sq ft is the full rectangle, walls to walls, so a closet inside that outline is already included. A closet outside the rectangle adds its own little rectangle on top — add it as a row in the calculator.
How much flooring do I need for a 12×15 room?
Order for 198 sq ft — the area plus 10% waste for cuts. For diagonal or herringbone layouts use 15%, i.e. about 207 sq ft. The flooring calculator turns that into boxes for your specific product.
